I'm a 28-year-old woman currently residing with my mother due to my financial constraints, as I'm still completing my education with a college grant. My upbringing in the Adventist Church left me with some deep-seated emotional issues.

Since my father's death, my mother has entered a relationship with a new partner who practices an Afro-Brazilian faith. While I've expressed my struggles with religious discussions due to my Religious Trauma Syndrome diagnosed by a therapist, he has repeatedly tried to share his spiritual experiences with me. Despite requesting respectfully to refrain from this topic when we're alone, he has ignored my requests multiple times, causing me significant distress.

This repetitive breach of my boundaries led to a confrontation where I was firmer after he once again approached me with the same topic. I believed he understood my point after he became silent, perhaps feeling ashamed. However, he later complained to my mother, claiming I was rude, which resulted in a harsh rebuke from her accusing me of immaturity and intolerance. I explained my side, agreed to apologize for the tone but not for maintaining my boundary.

I personally apologized to him but reiterated my stance on avoiding religious conversations for my mental health's sake. He dismissed my approach, suggesting that adulthood involves tolerating discomfort. This makes me wonder if I'm really in the wrong here.

Imagine the drama this situation would cause if it played out on a reality show! The cameras would zoom in on our heated discussions, and viewers would probably be split. Some might applaud my stance on mental health boundaries, while others might criticize me for not being more accommodating. The producers would eat up the tension and the mixed reactions from the audience would add even more spice.

Am I being unreasonable here?

Is setting strict personal boundaries justified?
